The letter said in sparkling green letters. She wasn't happy, in fact, she felt like ripping the letter in to pieces. Nymphadora's family didn't exactly like magic. When her older brother read it, he had snatched the letter and showed it to her mother and father. Oh and, Nymphadora, she... got disowned. 

Nymphadora's mom had experience with a wizard before, in fact, it was her mom's own brother. Nymphadora was adopted. She never knew who her real parents are.

Nymph paced along the street, thinking of how to get out of this mess. Suddenly, she felt something grab her arm. Out of instinct, she twisted out of the person's grip and punched it square in the face. Nymph pressed her chakaram against the figure's throat. She was taken aback when she saw that the person was a boy, about the same age as her.
"Ouch, did you really need to do that?" The boy said, recovering from the punch.
Nymph rolled her eyes. " What did you aspect me to do? Give you money? Treat you a cup of coffee? You really are pathetic. And seriously, I didn't even punch you that hard. Tsk, tsk."
"Actually, that was exactly what I aspected you to do. My name is Colin, what is yours?" The boy said sheepishly.
"And why should I tell you?"
"Because I am one of you too. I am a wizard. You are a witch. I already got my stuff and I will help you get yours too."
Nymph was suddenly behind his back. Chakaram pressed against the boy's throat, Nymphadora asked, " how do you know?"

Colin grinned, "I didn't, I only assumed. But now I know, since you kinda just told me."
